[QUOTE="megalomaniac, post: 5616914, member: 2805"] When nest is initiated, she basically just visits the nest site for 30min to an hour each day to lay an egg until her clutch is complete (12 to 14 eggs on average). Once her preset number of eggs is reached, she begins to set (incubate) which causes the embryonic disc on the yolk to go from a state of suspended animation to actively developing. It requires mostly consistent temperatures of approx 99.5 degrees for the poult to develop properly. Incubation lasts 28 days. During the first 21 to 24 days, the hen will take a break from setting for a few minutes up to 30 minutes (depending on ambient temperatures) to grab a drink and a bite to eat at least once daily, sometimes twice... but returns to the nest to continue incubation. She stays on the nest all night without leaving during incubation, turning and rotating the eggs throught the day and night to ensure proper development and exercise the developing poults. The last part of incubation prior to actual hatching is called 'lockdown' which begins day 21-24 (usually closer to day 24).
